I expect to be winning this hand a lot OTR. He rarely has Kx, has some flushes but not all of them, almost never has a straight (because you block them) and has a lot of Tx and Jx. Also he is probably never bluffing on this board with a BXR line so I think we can go for a thin value bet here. Checking is totally fine too. If we check and villain bets, it's very player dependent. It depends on how thin villain will go for value and how many Kx and flush combos they get to the river with. In general, passive players will get to the river with a stronger range than an aggressive villain who will bet the turn with most of his flush draws and Kx.

river is a b/f in my book, but its close and I dont blame you for xf really

I think villain bets most of his kings on the turn so I would feel pretty confident when he checks back the turn.
My plan would be to x/c the river

Hand is played fine. We can bet very small otr if we want, but it's possible checking and allowing him to rando bluff us off 10x may make more money. He's more or less capped to Jx otr barring unlikely slowplays.

If you have KJs, It's wawb spot OTF, but with QQ it's not. If we don't have diamonds, I think we can get a value vs smaller PP, AQ, AJs, QJ, Tx. On this spot, we have diamonds and those hands call maximum 2 streets, so I like your checking OTF.
